SPECIFICATION forming part of Letters Patent N o. 704,515, dated July15, 1902.

Application filed March '7, 1902. Serial. No. 97,146. (No model.)

To all whom, it may concern:

Be it known that we, BENJAMIN F. CLARK and WILSON SMITH, citizens of theUnited States, and residents of Cambridge City, in

the county of WVayne and State of Indiana, have invented a certain newand useful Im provement in Seats for Cultivators, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, which form part of our specification.

The object of our invention is to provide a seat for a cultivator whichwhen not in use may be pushed forward and out of the way. Our inventionrelates particularly to the manner of mounting the seat, and it is ofsuch a construction and arrangement that when the operator of themachine desires to Walk he may rotate the seat forward, so that it mayrest on the tongue, in which position it will be out of his road in casehe walks behind the cultivator.

In the drawings, Figure 1 is a perspective view of a portion of acultivator with our improved seat attached. Fig. 2 isa plan view of thearm supporting the seat. Fig. 3 is an inside elevation of a portion ofthe tongue, showing the manner of attaching the seatsupporting frame.Fig. 4 is a section of Fig. 3 on the line 4 4.. Fig. 5 is a detail viewof one of the ends of the seat-supporting frame.

A is the usual tongue, secured in any convenient manner to theaxle-frame B. The tongue A, as shown, is bifurcated at its rear 3 5 end,and the bifurcations project slightly behind the aXle-frame B and areprovided with downwardly-hanging bars C at their inner sides, which areheld in a vertical position by means of braces D, connecting the lowerend of said bars C with the tongue A. The bar C is provided with notches0, whose purpose will appear presently.

A swinging bar E is pivoted to the ends of the bifurcated tongue bymeans of a bolt pass- 5 ing through saidends and through the bar C, thebar E being held away from the bar C by means of a spacing-block e.

F is the seat, which is supported on the frame G, to which it is clampedin any con- 5o venient manner. The arm G is simply a bar any'requiredvertical position.

.the arm G at points near its ends, as seen in Figs. 2 and 5, the plateH projecting beyond the vertical leg of the angle-plate. The ver- 6otical legs of the angle-plates H are of the same thickness as theswinging arms E and are at a distance froin the hookg equal to the widthof the swinging arm E, so that the space It is of such a size that theswinging arm E may slide in it. The horizontal leg of the plate H isadapted to fit in the notches c in the bar C.

To attach our improved seat to the machine, the bolts are applied to therearends of the bifurcated tongue, and the armsC and braces D are fixedin place. The bars E are then slipped into the spaces hat the ends ofthe'Y- shapediarm G, and the arms E are boltedin place, with the washerse separating them from the barsC, as seen in Fig. 2. Theends of the armGare then slipped down the bars E' untilthe horizontal leg of theangle-plate Hengages one of the notches c, in which position it is held,so as to support the party occupying the seat F. Then it is not desiredto use the seat F, it is simply rotated forward, so as to rest upon thetongue A, the

arm E swinging about the bolt 6 as a center,

as seen in dotted lines in Fig. 3. The notches cfurnish a means forup-and-down adjustment of the arm C, so as to put the seat in Theswinging arms E are booked in shape at theirlower ends, as seen at70,l30 prevent the-Y-shaped arm from droppingcompletely. These hooksalso perform the same function as the notches 0 when the arm G is movedto its lowest position.

We have described ourimproved' seat as atta ehed to a cultivator; but wedo not wish to 5 limit ourselves to its use with a cultivator, as ofcourse it is evident that it may beattached to a variety of implements,where its use would be of advantage, nor do we wish to be limited to theexact construction shown xoo and described, as it is apparent that thismay be varied without departing from the spirit of our invention. Forexample, in some inachines it might be found thata single bar instead ofthe Y-shaped bar might be used, in

which case only one set of the arms 0 and E would be necessary.v Inaddition, the construction for forming the opening or slot h to receivethe swinging arm E may be varied, and also the construction describedfor form ing the horizontal projections engaging the notches a may bereplaced by any equivalent construction.

' Having thus described ourinvention, what we desire to claim as new andto cover by Lettersv Patent is 1. As a means for supporting a seat,vertical arms rigidly connected to the frame of the machine and providedwith notches,swinging arms pivoted to said vertical arms, a Y- shapedarm supporting the seat at the rear and having its forward ends engagingsaid swinging arms and provided with a horizontally-projecting plateadapted to engage the notches in said vertical arm, substantially as andfor the purpose described.

2. As a means for supporting a seat,a vertical arm rigidly connected tothe frame of the machine and provided with notches, a swinging armpivoted to said vertical arm, a second arm supporting the seat at itsrear end, and having its forward end engaging said swinging arm, andprovided with a horizontally'projecting plate adapted to engage thenotches in said vertical arm, substantially as and for the purposedescribed.

3. In combination, a vertical arm rigidly connected to a frame andprovided with notches, a swinging arm pivoted to said vertical arm, asecond arm supporting the seat at its rear end and having its forwardend bent into hook form and engaging said swinging arm, and a horizontalprojection on said second arm adapted to engage the notches in saidvertical arm, substantially as and for the purpose described.

4. In combination, a vertical arm provided I with notches and rigidlyattached to the frame of the machine, a swinging arm pivoted to saidvertical arm, a second arm provided with a seat at its rear end and witha vertical slot at its forward end through which passes the saidswinging arm, and a horizontal projection on' said second arm adapted toengage the notches in said vertical arm, substantially as and for thepurpose described.

5. In a cultivator, vertical arms provided with notches and rigidlyattached to the frame, swinging arms pivoted to said vertical arms, aY-shaped arm carrying a seat at its rear end and having grooves at itsforward ends in which are located the said swinging arms, and horizontalprojections on the forward ends of said Y-shaped arm adapted to engagethe notches insaid vertical arm, substantially as and for the purposedescribed.

6. In a cultivator, vertical arms provided with notches and rigidlyconnected to the frame, swinging arms pivoted to said vertical arms, aY-shaped arm having its forward ends located between said vertical armsand said swinging arms, and provided with angular extensions adapted toengage'said swinging arms,angle-plates secu red at the forward ends ofsaid Y-shaped arm, with their horizontal legs in a position to engagenotches on said vertical arms, plates forming a groove to receive saidswinging arms and an adjustable seat mounted at the rear of saidY-shaped arm, substantially as and for the purpose described.

'7. In a cultivator, vertical arms provided with notches, swinging armspivoted to said vertical arms, a bifurcated arm carrying a seat at itsrear end and provided with hooks at its forward ends which engage saidswinging arms, and horizontal projections at the forward ends of thebifurcations which are adapted to engage the notches of said verticalarms, substantially as and for the purpose described.

8. In combination, a vertical arm provided with notches, a swinging armpivoted to said vertical arm, a bar supporting a seat at its rear endand provided at its forward end with a slot by means of which it mayslide on said swinging arms, and also provided with a horizontalprojection adapted to engage the notches in said vertical arm,substantially as and for the purpose described.
